Hi John,
Today's linux-next merge of the wireless tree got a conflict in
net/mac80211/mlme.c between commit
b054b747a694927879c94dd11af54d04346aed7d ("mac80211: fix deauth before
assoc") from Linus' tree and commit
36b3a628a4e85d002ee8813ebd2a5caef6d3c1a7 ("mac80211: common work skb
freeing") from the wireless tree.
Just context changes. I fixed it up (see below) and can carry the fix
for a while.
